The Cassettes are controlled via the head end. Each Cassette has two inputs and one HF output, as well as an integrated multi-transport flow processor for stuffing, PID pass, drop and service filtering. For thes

2.3.1 Manual display of the software version If necessary, you can call up the display of the software version of the control unit manually: � Hold down any two keys of the control unit simultaneously until the display goes dark and the software version, e.g. “V.34”, is displayed. 2.3.2 How the TP module works When converting the QPSK-modulated signal to a QAM-modulated cable signal, the demodulated data stream can be accessed via the integrated TP module. This data stream, also called tran

2.3.3 Explanation of the term “symbol rate” High-quality modulation methods like QPSK and QAM can encrypt several bits as a single transferred and received symbol. The user data stream contains the audio and video signals of a station and is thus permanently assigned. If the value of the modulation and therefore the number of bits per symbol is in- creased, the symbol rate falls compared to the user bit rate. Formulae for calculating the output symbol rate “SR (A)” at a fixed input symbol r

Note: The operating software of the Cassette can be updated via the socket “RS 232” 3 (9-Pin-Sub-D) by means of a PC or notebook. Use the “BE-Flash” software as the update software. You can make drop and pass filter settings in the channel strip “B” using the “MTP” PC software.

Set the other Cassettes listed in the same way. 5.1 Preparation Notes: Using the menu “LEVEL CONTROL” the Cassette generates an equally powerful HF carrier on the video carrier frequency of the channel. In this way, the Cas- sette‘s level can also be set with an analogue TV test receiver set to the video carrier frequency of the channel. In order to prevent i

Setting the input frequency (transponder frequency) Notes: – If three dots “ … ” appear in the second line of the display, the Cassette is in the “station search” mode. Please wait until the process has finished. Once the HF receiver has synchronised to the input signal, any offset to the target frequency is displayed in MHz, e.g. “– 0.4”. – If a question mark “?” appears in the second line of the display, there is no input signal present. Check the configu- ration of the antenna system
